C#显示错误消息
try
{
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
Delphi显示错误消息
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
var
int1: Integer;
begin
try
int1 := StrToInt('A');
except
MessageBox(0,PWideChar(Exception(ExceptObject).Message), '小志智能家居系统', MB_OK);
end;
end;
end.
本文对比展示了C#和Delphi两种编程语言中错误消息的显示方式。C#使用try-catch语句捕获异常并通过MessageBox显示错误信息;Delphi则通过类似的try-except结构,并利用MessageBox函数展示错误详情,提供了跨平台的错误处理示例。
